I know what you were talking about. It was two difference scenarios. The comic Batman wasn't crippled on a cane.

No, it's called lazy writing. You don't learn a thing about Bruce Wayne from watching the Joker.

Yeah all those riddles Joker sent Batman in TDK. Totally Riddler like. Joker is ALWAYS ahead of Batman. That's one reason why he's his greatest villain. Here I'll give you a very accessible example for you to check out yourself:

It's all about the first encounter Batman and Gotham have with the Joker, and Batman is completely overwhelmed by him, Joker is always one step ahead of Batman and the Cops, the city is thrown into chaos and fear of him, just like in TDK.

As Batman said in BTAS; "Normal criminals usually have logical motives. But the Joker's insane schemes make sense to him alone. That's why he's so unpredictable".

(Also the BTAS quote reminds me a bit of Alfred's "Some men just want to watch the world burn..." great speech)
